摘要: 本试验对猪精液冷冻保护液中添加咖啡因的作用进行了研究,并优化冷冻-解冻程序,提高0.5 mL细管猪精液冷冻解冻后的质量。在预先设计稀释液配方的基础上,使咖啡因终浓度为0、0.2、0.4、0.6 mg/mL,选择最佳咖啡因浓度,选出最优组合与传统的TCG稀释液和商业用Androhep〖XC1.TIF〗CryoGuardTM冷冻稀释液进行比较,比较3种不同的冷冻曲线对猪冷冻精液解冻后精子品质的影响,最后对38 ℃下30 s、50 ℃下13 s 2种解冻方法进行比较。结果表明,咖啡因浓度为0.2、0.4 mg/mL的精子冷冻后活力、质膜完整率、顶体完整率显著高于0、0.6 mg/mL(P<0.05),最佳添加浓度为0.2 mg/mL;预设计的稀释液配方及冷冻方案优于传统的TCG法(P<0.05),但与Androhep〖XC1.TIF〗CryoGuardTM稀释液(美国商业用)有一定差距(P<0.05);A曲线在猪精液冷冻-解冻后活力、质膜完整率和顶体完整率方面均显著优于B和C冷冻曲线(P<0.05);50 ℃水浴解冻13 s显著优于38 ℃解冻30 s(P<0.05)。

Abstract:

The aim of this study was to investigate the effect of supplementation of caffeine in freezing extender on frozen-thawed semen quality. Optimize freezing and thawing protocol in 0.5 mL straws. Supplementation of caffeine directly into preliminary design freezing extender, the concentration of caffeine was 0, 0.2, 0.4, 0.6 mg/mL, determined the best concentration of caffeine. Then compared with the traditional TCG extender and the Androhep〖XC1.TIF〗CryoGuardTM extender, comparison of three different freezing curves on the frozen-thawed sperm quality. The frozen sperm samples were thawed by warming them at 〖HT〗〖ST〗〖WT〗〖HJ〗


〖WT5”BZ〗37 ℃ water bath for 30 s and 50 ℃ water bath for 13 s. The results showed that there was a significantly higher percentage of progressive motility, membrane integrity and acrosome integrity in caffeine supplemented groups than control group(P<0.05), the best concentration was 0.2 mg/mL. The preliminary design was better than the TCG (P<0.05), but it had a significant variance with Androhep〖XC1.TIF〗CryoGuardTM extender (P<0.05). Three different freezing curve had different influence on sperm quality parameters. Freezing curve A had a higher percentages of TMS, PMI and NAR of spermatozoa than B and C (P<0.05), thawed at 50 ℃ for 13 s was better than 38 ℃ for 30 s.

Key words: boar semen; caffeine; freezing curve; freezing rate.
